deep-fusion-vs-plugin-install-for-skill-upgrades

When integrating external repos/tools into an existing skill ecosystem, merging intelligence into existing skills (‘Deep Fusion’) avoids Zero Ambiguity violations — two competing design intelligence sources (e.g., Impeccable anti-slop + frontend-taste anti-slop) create skill overlap and context window bloat. Installing as separate plugins causes Law #2 violations. The correct pattern: absorb non-overlapping intelligence into the closest existing skill, not add a parallel skill.
